I have a 1974 corvette that i am building a 406 for. Give me your opinions on my combo. 406 with 3.75 stroke cola crankshaft 5.7 scat cap screw rods mahle powerpack pistons with a set of sportman II heads. The camshaft is an elgin 1131 240 int 250 ext .520 with either a victor jr or an rpm air gap and i am not sure on carb yet. The car is auto transmission that will be rebuilt and probably a 3000-3200 stall. How much hood clearance trouble will i have? Also i was thinking about going with a hydraulic roller in stead of the solid flat tappet cam.

With that victor jr the hood will hit and with the air gap also. Your going to have to run a orignal style drop base for the filter with whatever you run. I ended up with a performer rpm on my 74 and the hood still hit. This was without the drop base filter base though. JMO

Can you do anything with motor mounts to get the engine a little bit lower in the car?

Check with the guys in the C3 section at www.corvetteforum.com because I am sure the same question has been asked more than once. The best I can recall is that the air gap will not work but others with a drop base air cleaner will.
